To report a case of macular telangiectasia (MacTel) showing the features of type 3 disease in one eye and type 2 disease in the other eye.
Descriptive case report.
A 50-year-old well-controlled diabetic man presented with complaints of distorted vision in the right eye for the past 1 year. His best-corrected visual acuity in both eyes was 20/20, N6. His anterior segment findings were normal. The right eye fundus showed an irregular perifoveal greying and a localised dark patch temporally inside the perifoveal region. Few microaneurysms were seen on clinical examination. No hard exudates were noted. The left eye fundus showed a few microaneurysms with minimal perifoveal greying temporally. Imaging with confocal blue reflectance, fluorescein and optical coherence tomography angiography confirmed the diagnosis of MacTel type 3 in the right eye and type 2A stage 2 in the left eye with mild non-proliferative diabetic retinopathy in both eyes.
This case raises the possibility that type 3 disease could be a progressive non-proliferative form of a pre-existing type 2 MacTel disease.
报告一例一眼表现为 3 型疾病特征，另一眼表现为 2 型疾病特征的黄斑毛细血管扩张症（MacTel）病例。
描述性病例报告。
一名 50 岁的糖尿病控制良好的男性，因右眼视力扭曲 1 年前来就诊。他双眼最佳矫正视力均为 20/20，N6。他的眼前段检查正常。右眼眼底可见不规则的周边灰变和周边区域颞侧局部暗斑。临床检查可见少量微动脉瘤。未见硬性渗出物。左眼眼底可见少量微动脉瘤，周边颞侧有轻微灰变。共焦蓝反射、荧光素和光相干断层扫描血管造影成像证实右眼为 3 型 MacTel，左眼为 2A 期 2 型，双眼均有轻度非增生性糖尿病性视网膜病变。
本例提示 3 型疾病可能是一种已存在的 2 型 MacTel 疾病的进展性非增生性形式。
